I am experiencing the same problem (hardy amd64). If I specifiy the mtu in the a /etc/ppp/peers/file and use "pon file" to connect to the vpn, mtu is set correctly. But with network-manager, even if "mtu 1300" is specified on the command line of pppd, the setting is not effective.
-- network-manager-pptp does not change mtu even if specified https://bugs.launchpad.net/bugs/151112 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
